BEARING-BOX FOR SHAFT-HANGERS.

SPECIFICATION formingpart of Letters Patent No. 71 1,620, dated October21, 1902.

Application filed June 18,1902. Serial No. 112,197. (No model.) A

To all whom it may concern.-

Be it known that we, WILLIAM H. ERMEN- TROUT and LEwIs V.HALBERSTADL'OIILIZGHS of the United States, residing at Reading, in

the county of Berks and State of Pennsyl- Vania, have invented certainnew and useful Improvements in Bearing-Boxes .for'Shaft- Hangers; and Wedo hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to improvements in bearing-boxes forshaft-hangers; and the object of the invention is to facilitate thelubricating of the shaft-bearing therein.

' The invention consists of the box to contain the lubricant and thebearing therein, with means for conveying the lubricant to the workingface of said bearing, and it is in this means that the inventionconsists:-

The invention is fully described in the following specification andclearly illustrated in the accompanying drawings, in which- Figure 1 isa plan view of the box and hearing with the cover removed. Fig. 2 is alongitudinal sectional View taken on line a: as, and Fig. 3 is avertical sectional view taken on a line 'y y, of Fig. 1

A is the box for casing and is of ordinary construction with twodepressions or circumferential grooves a, formed in its inner face.

B is the bearing, and it ismounted on a cen- 3 5 tral pivot in the baseof said box. The outer wall of said bearing is formed with depressionsor circumferential grooves b, similar toand registering with the groovesa in the casing. This bearing Bis provided with a lining 40 C,preferably of soft metal. Two openingsE are formed in both the bearingand the lining about an equal distance from either end, and

in these openings are placed Wicks e, of suitable conducting material,through which the lubricant may be carried from the bearingbox to thebearing-surface of the lining by means of capillary attraction. In thecircumferential grooves around the bearing formed by the openings a andb. are placed flexible rings capable of revolving thereon. These ringsare prevented from longitudinal displacement by means of saidregistering grooves. Obviously we may employ chains or any otherflexible rings, if desired; but in our drawingsaccompanying thisapplication we'have only illustrated the use of rings.

It will be seen that with our present construction either mode ofconveying the lubricant to the bearing-point may be employed.

If for any reason the use of the rings or chains is not satisfactory orif it should be desired to dispense with their use, then the wickalone'may be employed on the same hearing, or vice versa. If, on the otherhand, it is desired to produce an unusually free or voluminous flow ofoil, both of the described means may be used at the same time and in thesame bearing.

Having thus fully described the invention and its application, what weclaim, and desire to procure by Letters Patent, is

A bearing-box for shaft-hangers, comprising a sectional casing, saidcasing being provided witha plurality of internal circumferentialgrooves, a bearing mounted in said I casing on a central pivot, andprovided with a plurality of external circumferential grooves adapted toregister with the grooves in the casing, said bearing also beingprovided with a plurality of apertures, in its base in prox- 8o imity tothe grooves, a lining in the base of the bearing, also provided withapertures, adapted to register with the apertures inthe bearing, wickssecured in the registering apertures, and rings surrounding the bearing,said rings being held in position from longitudinal displacement bymeans of the registering circumferential grooves.

In testimony whereof we affix our signatures in presence of twoWitnesses.
